Turbo

[rambler]

As above....

In last few days,ive noticed i can actually now hear my turbo " spin up " very audibly.

As i accelerate ,from about 2'500 revs i can hear it " whistle " when i floor it.

And the more it pulls , the more it " whistles ".

Happens all times when i accelerate ,in all gears, engine hot or cold.

Ive got no smoke issues....it still pulls just fine...and strongly.

I also hear quite a hiss when it spins up,as if there is an " air leak "....could that be what i'm hearing ?

Question is......should i be able to hear it....easily ?

Depends on how big an air leak it is.

You can hear them more in cold weather Rambs.

I've had this once, a long time ago, on our '03 D4D. One of the large hose clips on the air duct from the turbo (to and through intercooler) had worked loose, and was blowing/whistling. Check all the clips for a start.

Also quickly check the air cleaner - element and lid in place and OK ?

Have had a quick check of all the hoses i can see ,and checked the air cleaner etc etc....all ok ( as far as i can make out )....bizzare thing is.........

It is actually the same rasping noise,that i thought could have been a heat shield recently,i think........it is...air escaping under pressure,.......from somewhere.

This hissy rasping noise....matches the engines revving and sounds worse when the turbo cuts in......but now doing it .....every time i take it past 2000 ish revs...

Could the turbo be on its way out ?...as i mentioned there's no smoke,and it pulls ok....it just hisses quite badly when it pulls.

Can you get someone to rev it whilst you have a gander under the bonnet Rambs? Might be able to narrow down where the hissing is coming from. Have you considered an exhaust leak?

[Big Kev]

Exhaust leak or catalyser innards collapsed and partially blocking outward pressure was my guess.....?

I could ask my mother.....as i live with her ( bless her ).

Can you smoke test the system ?

In plumbing we sometimes smoke test drainage to see if there are any leaks...same principal ?

I can get some smoke pellets and put one of them in the air filter housing ( enough smoke to fill a household garage ...easily ).....or maybe even a smoke match ?..we use both these on flues...to check the draw.

What would be the symptoms if my turbo was going wrong please ?

They usually smoke quite badly or lose power. It is probably leaking round one of the gaskets Rambs. They leak a bit then burn away.
